r To all whom it may concern Be it known that L`RroHA-nn LESTER WIL-cox, a citizen of the United States, residing at lvVaterbury, in thecounty of New Haven and State of Connecticut, have invented certain newand useful improvements in D ie- Blocks, of which the following is aspecification, reference being had therein to the accompanying'drawings.

lhe invention herein shown and described relates to a die block of thetype used in a heading machine'for holding the dies, and has for itsobject, among other things, to so design and construct lthe severalparts of the block that the body member thereof may be attached to theheader and not require removal therefrom to adjust the dies, or for anysimilar reason, and to connect there with a cap or cover that may bereadily moved, into and out of its closed position without separationfrom the body member and with the minimum labor and inconvenience.

front view; Fig. 3 is a With these objects in view, my inventionconsists in the die block, having certainv details of construction andcombinations of parts, as will be' hereinafter described and moreparticularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designatelike parts in the several igures; Figure 1 is a side view of my improveddie block; Fig. i. is a plan view; and Fig. 4 is a sectional view of thecap or cover, taken upon line A-B of Fig. 2.

The prior art discloses generally two types of header die blocks, onetype requiring removal of the block with its connecting parts, as aunit, from the header to have access to the dies, an operation requiringmuch labor and strength, and involving serious diiiculties in the finerelative adjustment of the several parts; another type, differing onlyin that the body of the die block is held within the header while thecove'r or cap is removed therefrom.

all of the advantages of the latter, of the above described types of dieblocks and the added advantage of a movable cap or cover that can bemoved into and out of its closed 1 position without removal from themachine, with the minimum inconvenience and withfout the aid of specialapparatus or an unusual amount of labor.

` In the embodiment of my invention there are two principal elements,the' first being the body member 1 that is secured within the header byany convenient means common in the art, and substantially L shape inside elevation, as shown in Fig. l, carrying an adjusting' screw 2,common to all types of die blocks, whereby the body member may beadjustedy within the header. rlhe other principal element is the cap orcover 3 that is pivotally secured to the body. member l by the pin l.that passes through the lugs 5 integral with the cap. to the body memberi in by the bolts 7 that pass through one wall of the body member and.slotted openings 8 in the cap', with nuts 9 threaded thereon. Theslotted openings S are of such size and shape as to permit the cap topass-over the bolts when the nuts 9 are removed and while being movedupon its pivot mounting.

its closed position fhen the cap is in its closed position there is anopen space l0 between the underside thereof and the horizontal portionof the body member, in which the dies not shown) are movably mountedupon the hardened plate 13, being held against endwise movement by theplate il that is secured by screws l2. The wire being fed to the diespasses through the hardened bushing 14 fixed within the vertical portionof the body member. A plurality of die separators l5, of the usual type,are slidably mounted within the cap 3, and are pressed downwardly byspring lingers connected with a iiXed part and not herein shown. In thefront face of the cap` 3 is a lifter opening 16 of substantially thesamediameter as that of the separators l5, and designed to receive one ofthe separators, as shown by broken lines in Fie. l, whereby `convenientmeans is provided for manipulating the cap or cover when it is desiredto swing the same upon its pivot mounting.

ln the drawings the several parts are shown in the relative positionsoccupied by them when the dies are mounted on the body member and heldagainst upward movement by the 'cap or cover. When it is This cap issecured desired to gain access to the dies, the nuts 9 are removed fromthe bolts 7, one of the separator pins is placed in the lifter opening6, and the operator grasps the projecting end thereof and swings the capnpwardly to its open position, shown by broken lines in Fig. l, theslots 8 permitting the cap 3 to pass over the end of the bolts 7. ,To return the cap or cover to its closed position, the operations arereversed and the nuts 9 threaded upon the bolts 7 With this improveddiet block, the minimum amount of labor is involved in obtaining accessto the dies, and at no time is the .i cap or cover removed from themachine.

The details of my invention may be varied, and I desire therefore tohave it .fined by the claims herein.

understood that I do not limit myself to the exact construction hereinshown and described, but claim all that falls fairly within the spiritand scope of my'invention as de- Ha'ving described my invention, what Iclaim as new and desire to secure by Letters Patent, is

1. In a die block, the combination with a body member; of a cappivotally connected therewith; and means for securing said cap to saidbody member in its closed position.

2. In a die block,A the combination with a, body member; of a cap orcover; means for pivotallyv securing the same to said body member; meansfor securing said cap to said body member against movement when in itsclosed position, said means permitting theA movement of the cap from itsopen to its lclosed position-without affecting the relative position ofsuch means in said body,

member.

3. In a die'block, the combinationwitha body member, having two walls atan an gular relation to each other; of a cap 5 means or pivotallysecl'iring saidcap to said body member; and threaded means for securmgsaid cap to said body member Whf'ni its' closed posit-ion.

4. In a die block, the combination with a' 'member; and means forsecuring said cap to said body memberwhen in its closedposition'.

5. In a die block, the combination with a body member, having two wallsat an anguthrough one-wall.. thereof and over the other wall; a cap; andmeans for pivotally securying said cap to said body member, said cappassing over the projecting end' of said bolt lwhile being moved fromits closed to its Iopen* position, and vice versa.` i 6. In 'a' dieblock, the combination with a body member,.havinig two walls at anangu-y `lar relation to each other; of one or morel '.bol'ts fixedtherein withv a portion thereof projecting through one wall thereof andover the Other-Wall; 'a' cap, having f a. llitter opening Yin one facethereof and slotted openings therethrough in such relative position withsaid bolts as to permit the same to pass therethrough; and means forpivotally securing said cap to said body member.

- lar relation to each other; o a retaining bolt v In testimony whereofI aiiiX my signature in Apresence of two witnesses.
